To aZZ-whmn it may concern:

Be it known that I, THOMAS H. SYMING- iron, a citizen of the UnitedStates of America. residing at the city of Rochester, county of Monroe,State of New York, have invented certain new and useful Improvements inEnd Constructlon, of which the following is a specification.

end of the car.

This invention relates to a plate and angle construction to be appliedto the sills of wooden cars. i

The replacement of antiquated and worn out draft gears on the old Woodenframe freight cars is at present an important item in railway equipmentand the application of the modern types of draft gears to the woodenframes in a manner which will en-- able them to withstand the-increasedbuffing and drawing stresses to which these parts are subjected undermodern conditions of heavy trafiic, involves various problems of 'the'greatest importance. Great difficulty is encountered in so attaching thecheek plates to the wooden sills that the sill will not be split andshattered with the result that the cheek plates become loose or detached.and the draft gear fails completely.- Also as the draft gear is mountedbelow the sills, there is a tendency for the sills to give downward atthe ends and break at the bolster.

' the depending portion of the draft plates, bolts being ordinarily usedfor this purpose. In the present instance, a beam built 'up of platesand angles or channels 1s preferably substituted for the old woodenbolstern The draft plates referred to, as carrying the cheek plates, arereinforced along the top and bottom edges of the cheek plates, by meansof angles or other stiffening members, andthese angles, part or all ofthem in the preferred form of the invention, as' Well as the platesthemselves, Wl'llCll arenotched or shouldered for this purpose, abutagainst the bolster and at the front, and the"; top portion of the draftplate, which projects upward between the sills, abuts against the frontcross-sill. At the rear, the draft plates extend over and beyond thebolster. belngu'einforced at the bolster to prevent breaking of thesills over the bolster as is the tendency of the former structures.

Preferably the cheek plates which receive the drawing and buffingstresses, are secured to the depending portion of the draft plates overthe reinforcing members previously referred to, and the rivets or boltspass through the draft plates, cheek plates and angle irons so that thewhloe structure is exceedingly rigid, durable and permanent and cannotbe displaced except by the destruction of the entire under frame.

A draft gear construction applied to a wooden under frame by means ofthe device of my invention, is shown in the accompanying drawings, inwhich Figure 1 is a view half in plan and half in horizontal section onthe line 1, 1 of Fig. 2; Fig. 2 is a. vertical central cross-section;Fig. 3 shows a draft plate in elevation; Fig. 4: is a front view; andFigs. 5 and 6' are transverse sections, one on each side of the centrallongitudinal vertical plane. taken on the lines 5 and 6 respectively ofFig. 1.

Having reference to the drawings b means of characters applied to thedifferent parts; the under frame is shown fragmen tarily as consistingof center sills 1, running longitudinally of thecar on each side of thecenter about a foot apart, a front cross-silt 2 and a bolster 3 beneaththe sills secured thereto and extending from side to side of the car,

While the construction which is the subject of the invention-may be usedin connection with any preferred form of draft gear, in the presentinstance, it is shown as applied to a three-key link draft gear of theFarlow type, having three cross-keys, 4, 5 and 6, the front onebeingseated in a slot 7 in the drawbar 8 and normally occupying the centersofslots 9 in the cheek plates and extending through slots 10 in theforward ends of the links. The second key .carries the front follower 11and passes through the middle slots 12 in the links and 18 in the cheekplates. The rear key carries the rear follower 14 and passes through therear slots 15 in the links and 1.6 in the cheek plates. Between thefollowers is the usual spring or other shock-absorbing means 17.

The draft plates 19 which are of a width exceeding the width of thesills to a considerable extent, are secured to and overlie the innerfaces of the sills at the front and rear ends so that the lower portionsof the draft plates extend well below the sills.

The cheek plates 18 are secured to the depending portions of the draftplates beneath the sills, the draft plates in theform of the inventionshown, being slotted at 20 to admit the flanged portions 21 whichsurround the slotted openings. in the cheek plates. Above and below theslotted openings are stiffening members 24: and 25, see

particularly Figs. 5 and '6. These are in the form of angle ironsand'extend in a horizontal direction and are preferably interposedbetween the cheek plates 18 and the draft plates 19, the upper angleiron 24: having a flange-24! secured to the bottom of the sill. Asshown, the member 24 is the longer, and abuts at its rearend against thebolster 3. The draft plates and incidentally the angle irons, 24 and 25are tied together by means of. a tie-plate 26 shownas provided with endflanges, the latter each having two bolts, which pass through the lowerportion of the draft plates and the lower angle irons.

At the forward end, the draft plates have secured to theman angle plate27 which bears against the end sill 2 and the depending portions of thedraft plates terminate as shown, with a vertical shoulder 28 justforward of and in contact with the front The upper stifiening edge ofthe bolster.

bars or angle irons 24, also terminate at this point, but theupperportion of the draft plate extends well to the rear, over the topof the bolster, being secured to the sill throughout theirlength, andthe draft-plate is reinforced at this point by means of a cover'plate 29which affords a seating surface for the heads of the bolts which passthrough the wooden sills, stiifens thedraft. plate and resists thedownward bending movement in buffing. Thus the draft plates which carrythe cheek plates are rigidly'secured at the front and rear so that theyhave a thrust against the front sill in drawing and against the bolster.in bufling. They are further'stiffened at. the points of greatest stressby means of the angle irons; 24 and Q5 and the upper'anglcs abut-attheir rear y, ends against the bolster so that the buffing stresses,which are the heaviest stresses to -mitted directly to thebolster by wayof,

which the draft gear is subjected, are transrigid members amplysufiicient to receive and 'resist them, and the tendency which formerlyexisted to bend the forward ends of the sills down and break them inbuffing v is completely overcome.

The drawing stresses, which are less in magnitude, are fully taken careof by the against the igiaaaw direct thrust against the crosssills aswell as the rigid attachment of the whole top portion of the platedirectly to the inner face of the Wooden sill.

I have thus described my invention spe-' ciiically and in detail so thatits nature and the manner of using it may be; fully understood by thoseskilled in the art. However,

the specific terms herein are-used in their descriptive rather than intheir limiting sense and the scope of'the invention is dcfined in theclaims 1 I cla1m 1. A. center construction comprising cendepending draftplates secured to the inner faces of the sills, parallel angle ironssecured to theouter faces ofthe plates beneath the sills, having oneflange horizontal, the

horizontal flange of the upper angle iron being secured to the bottom ofthe sill, cheek plates overlying the vertical flanges of the angleirons. and fastened to both the angle irons and: the draft plates.

3. A center j construction consisting of wooden center sills, an endsill and a bolster, draft I plates secured to the inner faces of thecenter sills each having a depending portion below the sills, the rearends of the plates abutting. against the bolster and the front e'ndsagainst the end sill, cheek plates .secured to the draft plates beneaththe sills and horizontal reinforcing emb ers'in the form of angle ironssecured to" the top, and

bottom edges respectively of'tlie depending portion of each draft plate,the upper angle irons having horizontal flanges secured to the bottomsof the draft sills.
